Faulty or Flashing Display
Probable causes:
•
Power supply too low
•
Too much load on same line
•
Defective display power supply on interface board
•
Possible static problem (to correct, spray with staticide)
An excessive load or excessive consumption on the same line may be causing problems. Connect the
device to a specially fused power supply line or remove the other power-consuming devices from the
mains.
11.7
Serial RS-232 Interface
Possible causes of a serial interface malfunction are:
•
Defective wire connection in adequate pin allocation for the components
•
Incorrectly set component protocols (e.g. treadmill, PC, EKG, Spiroergometry)
•
Improperly configured connection settings between the components (COM Port)
11.8
Sources of Electromagnetic Interference
Close proximity to, for example, X-ray equipment, powerful motors, or isolating transformers must
be avoided because of possible electromagnetic interference.
Electromagnetic interference can affect the operation of your treadmill.
11.9
Interference of the POLAR® Heart Rate Monitor
During the transfer of data from the transmitter to the receiver the POLAR® heart rate monitoring
may receive interference, which is triggered by other devices in the proximity of the treadmill. The
most common causes for this are:
•
PC screens, computers, radio systems of all kinds
•
High tension power lines
•
Intense light exposure
•
Strong magnetic fields
